You get SPAL fans, the best aftermarket cooling fan, mounted on a custom built aluminum shroud, which are easily removable, combined with an adjustable electric fan controller and an upper radiator hose inline adapter, both manufactured by Davies Craig. The custom aluminum shroud is designed to fit directly to the OEM radiator in the 3.9 , 5.2, 5.9 liter gas engine trucks. 

  Our electric radiator fan units are designed as a drop in direct fit unit with all hardware included to make installation a breeze.  We have included all the necessary brackets for mounting the radiator coolant recovery bottle and the windshield wiper fluid reservoir, maintaining the original positioning for a factory look and finish. The adjustable dual electric fan controller, produced by Davies Craig part #0445, comes with a liquid style temp sender probe that uses a compression type fitting which be secured into the inline hose adapter that is also included in the kit. 

  The dual electric fan controller is fully adjustable and when setting the temperature it should be set 10 degrees above the thermostat temperature. This gives the controller the ability to cycle the fans properly.  When your programmed temperature setting is reached the left fan will start. If temperature drop is not met within 10 seconds then the right fan will begin to operate. Having this design implemented into the unit decreases the amperage spike that exists when the fans are engaged. In our tests and research we have found the OEM alternator is compatible with this upgrade. However, if you desire to upgrade your alternator with this install it is only going to enhance your experience with our product. 

This controller is designed with an override function (green wire) for A/C operation.  If A/C operation is not needed you can use it for overriding the temperature function of the controller. Conduct a road test monitoring engine temperature. If necessary, adjust the set/target temperature to suit your requirements.

This is one sweet setup! We have had customers express to us that they have seen  as much as 2-3 more MPG along with 3-5 degree cooler A/C vent temps at slow speeds and at idle. This will extend the life of your truck's A/C system by reducing the high side pressures your A/C system experiences under these same conditions with a mechanical fan. You are going to notice snappier acceleration, especially from a dead stop. This is due to the fact that you have removed the horsepower sucking, mechanical fan. 

  If you research newer trucks and Sport Utility Vehicles you will find that more and more auto manufactures are implementing electric radiator cooling fans into the vehicles they are producing today. The result you will find is that they are achieving better fuel economy, snappy engine response, and cooler cabin temperatures which results in less compressor failures with the A/C system. 

  To sum up, we feel we have found the right combination of premium components for the best quality, longest lasting, direct OEM fit, and the best looking trouble free unit on the market today.
